It is a sincere effort to furnish as much as possible details on polymeric composite insulator project including the application criteria, concept, types, technical requirements, manufacturing process, raw material required, testing etc.
In the transmission & distribution of electrical energy, insulator have the important task of creating a barrier between the live voltage & the ground while providing strong mechanical support, Insulators are used at various location in a power network & their insulation & mechanical characteristics must ensure long lasting barrier. Porcelain & glass type insulators have been used for over 100 years. More recently new composite (polymer) materials were introduced, The insulator are subjected to higher than usual level of one or more accelerating variables such as voltage, temperature & stress.
